Beam enlargement by mismatching the energy-dispersion function

Technical Report ·
OSTI ID:6907818
The natural beam size at the interaction point of a storage ring can be increased by operating the machine in a configuration in which the energy-dispersion function (/eta/-function) is nonrepetitive in the periodic cells of the machine lattice. This mode of operation has been studied in SPEAR and is being considered in the PEP design. The usual method of beam enlargement in SPEAR has been to operate the machine in a configuration with a large value of the /eta/-function at the interaction point, but with periodic /eta/-function in the cells. Some of the results of this study will be described. 4 figs.
